Hey guys, I found a web site showing how to upgrade the power supply on my X2 mill and am really happy with the results. I found a power supply on E-Bay for $25.00 and spent another $25.00 on an enclosure and a few other misc. parts.
The mill has a lot more torque verses the stock power supply, and the spindle speed went up from 1700 RPM to 2200 RPM in the low speed and from 4000 RPM to 6200 RPM in the high speed. You must have a belt drive to do this up grade because your stock gear train won't handle the extra torque.
I also made a new control box for the switches and is a little easier to use verses the stock unit. I don't have to turn the speed control switch every time I want to turn on and off the machine. The new box allows me to keep the speed setting and turn the motor on and off with a flip switch. I also added an extra switch for a future spindle light. There is a push button switch on the side for an E-Stop and it activates a relay inside to kill the power to the whole unit. The silver flip switch is for forward and reverse so I can use taps on the machine if needed. I also added a fan to the inside of the power supply and have the vent holes covered with a piece of window screen to keep unwanted things from entering.
Here is a link for the site.

Questions??? Feel free to ask.
P.S. If any one has a WORKING E-Mail for Harrison (The guy who made the web site) I would like to have it. He makes a belt drive kit for the X2 and I can't get ahold of him.
